Prosecutors presented formal charges against William Balfour in the deaths of Hudson's mother, brother and 7-year-old nephew, said Tandra Simonton, a spokeswoman for the Cook County state's attorney's office.

Balfour had been held on a parole violation since the bodies of Hudson's mother, Darnell Hudson Donerson, and brother, Jason Hudson, were discovered in their home Oct. 24.

The body of young Julian King, Balfour's stepson, was found in the back of an SUV three days later.
